You are what you eat: An empirical investigation of the relationship between spicy food and aggressive cognition

The popular saying “you are what you eat” suggests that people take on the characteristics of the food they eat. Wisdom from ancient texts and practitioners of alternative medicine seem to share the intuition that consuming spicy food may increase aggression. However, this relationship has not been empirically tested. In this research, we posit that those who consume “hot” and “spicy” food may be more prone to thoughts related to aggression. Across three studies, we find evidence for this proposition. Study 1 reveals that those who typically consume spicy food exhibit higher levels of trait aggression. Studies 2 and 3 reveal, respectively, that consumption of, and even mere exposure to spicy food, can semantically activate concepts related to aggression as well as lead to higher levels of perceived aggressive intent in others. Our work contributes to the literature on precursors of aggression, and has substantive implications for several stakeholders, including marketers, parents and policy makers.
